DESCRIPTION The LM139 series consists of four inde- pendent precision voltage comparators with an offset voltage specification as low as 2.0mV max for each comparator which were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power sup- plies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. These comparators also have a unique characteristic in that the input common mode voltage range includes ground, even though operated from a single power supply voltage. The LM139 series was designed to directly interface with TTL and CMOS. When oper- ated from both plus and minus power sup- plies, the LM139 series will directly interface with MOS logic where their low power drain is a distinct advantage over standard com- parators.

For operating at high temperatures, the LM339/339A, LM2901 and MC3302 must be derated based on a 125C maximum junction temperature and a thermal resistance of 175 C/W which appties for the device soldered in a printed circuit board, operating in astill air ambient. The LM139/139A/239/239A must be derated on a 150C maximum junction temperature. The low power dissipation and the On-Off" characteristics of the outputs keep the chip clissipation very small (Pp < 100mW), provided the output transistors are allowed to saturate. Short circuits from the output to V+ can cause excessive heating and eventual destruction. The maximum output current is approximately 20mA independent of the magnitude of V+. This input current will only exist when the voltage at any of the input leads is driven negative. It is due to the coltactor-base junction of the input PNP transistors becoming forward biased and thereby acting as input diode clamps. in addition to this diode action, there is also lateral NPN parasitic transistor action on the [C chip. This transistor action can cause the output voltages of the comparators to go to the V+ voltage level (or to ground tor a large overdrive) for the time duration that an input is driven negative. This is not destructive and normat output states will re-establish when TYPICAL APPLICATIONS LM139/A/239/A/339/A/2901-F,N MC3302-N the input voltage, which was negative, again returns to a value greater than ~0.3Vde. Positive excursions of input voltage may exceed the power supply level. As long as the other voltage remains within the common-mode range, the comparator will provide a proper output state. The low input voltage state must not be less than -0.3Vdc (or 0.3Vdc below the magnitude of the negative power supply, if used). At output switch point, Vo = 1.4Vdc, Rs = 02 with V+ from 5Vde to 30Vdc; and over the fuil input common-mode range (OVde to V+ -1.5Vde). The input common-mode voitage or either input signal voltage should not be allowed to go negative by more than 0.3V. The upper end of the common-mode voltage range is V+ -1.5V, but either or both inputs can go to 30Vdc without damage. The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the state df the output so no loading change exists on the reference or input tines. The response time specified is for a 100mV input step with a SmV overdrive. For larger overdrive signals, 300ns can be obtained, see typical performance characteristics section. The MC3302 has supply current specified with a voltage range of 5 to 28 volts.

For operating at high temperatures, the LM393/393A and LM2903 must be derated based on a 125C maximum junction temperature and a thermal resistance of 175 C/W which applies for the device soldered in a printed circuit board, operating in a still air ambient. The LM193/193A/293/293A must be derated based on a 150C maximum junction temperature. The fow bias dissipation and the On-Off characteristics of the outputs keeps the chip dissipation very small (Pp < 100mW), provided the output transistors are allowed to saturate. . Short circuits from the output to V+ can cause excessive heating and eventual destruction. The maximum output current is approximately 20mA independent of the magnitude of V+. This input current will only exist when the voltage at any of the inout leads is driven negative. It is due to the collector-base junction of the input PNP transistors becoming forward biased and thereby acting as input diode clamps. In addition to this diode action, there is also lateral NPN parasitic transistor action on the IC chip. This transistor action can cause the output voltages of the comparators to go to the Vt voltage level (or to ground for a large overdrive) fo- the time duration that an input is driven negative. This is not destructive and normal cutpu: states will re-establish when the input voltage, which was negative, again returns to a value greater than -0.3Vdc. 4. Positive excursions of input voltage may exceed the power supply level. As long as the iS) e a @ ~ 2 o other voltage remains within the common-mode range, the comparator will provide a proper output state. The low input voltage state must not be less than -0.3Vdc (Vdc below the magnitude of the negative power supply, if used). . At output switch point, Vo= 1.4Vde, Rs = 00 with V+ from 5Vdc to 30Vdc; and over the full input common-mode range (OVdc to V+ -1.5Vdc) The input common-mode voltage or either input signal voltage should not be allowed to go negative by more than 0.3V. The upper end of the common-mode voltage range is V+ ~1.5V, but either or both inputs can go to 30Vdc without damage. . With the LM293/293A, all temperature specifications are limited to -25C = Tas +85C and the LM393/393A, all temperature specifications are limited to 0C Tas +70C. The LM2903 is limited to -40C <= Ta <85C. The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the state of the output so no loading change exists on the refererice or input lines. . The response time specified is for a 100mV input step with a SmV overdrive. For larger overdrive signals, 300ns can be obtained, see typical performance characteristics section. . For input signals that exceed Vcc, only the overdriven comparator is affected. With a 5V supply, Vin should be limited to 25V max., and a limiting resistor should be usec on all inputs that might exceed the positive supply. 272 SiNEtiCS
